Staging

Some electric utilities require staging on electric heaters larger than 6 kilo-

watts. Therefore, the heater elements are turned on in 5 or 10 kW incre-

ments under control of the sequencers.

Ifstaging based on heat loss or demand is required, the use of accessory

outdoor thermostats is recommended. The heat sequencer wiring isde-

signed to be staged by breaking the 24V "Common" Leg (normally brown

or gray). Outdoor thermostats available through your wholesale supplier

allow the control of two or four stages of electrical heat.

Some indoor electronic thermostats may provide for multiple stages of

electric heat. When this type thermostat isused, it may be necessary to

break the 24V "Hot" leg of the sequencer (as fed from the "W' circuit at the

thermostat). This will require field modification of the control wiring and

should only be done by an experienced controls technician or electrician.

Install Heater

1. Shut OFF electric power at unit disconnect switch or service panel.

2. Remove the blower access panel from unit.

NOTE: Installation of field wiring and conduit for heaters to the

unit prior to installing the heater will simplify wiring of heaters.

3. From inside the blower compartment, remove the six screws on the

heater cover plate and save the screws. Discard the heater cover

plate.

The screws will be used later to mount the electric heat accessory

and its cover.

4. Remove the cardboard wrapper from the heater's elements.

5. Insert the heater into the heater/blower box. Exercise caution to

prevent damage to heater elements.

6.Secure heater to heater/blower box with four of the six screws re-

moved in Step 3.

Grounding

Permanentlygroundthe electricheataccessoryinaccordancewithlocalcodesandordi-

nancesandintheUnitedStateswithNationalElectricalCodeANSIINFPA70-1990orcur-

rent edition. Use a copper conductorof the appropriate sizefrom the electric heat

accessorytothe groundlug onthecircuitbreakerpanelas shownin FIGURE10.

Installing Wiring

Whenanelectricheataccessoryis installed,twoseparatefieldpowersuppliesMUSTbe

provided- one or more forthe electricheataccessoryandone for theunit.

1.Shut OFF electric power at unit disconnect or service panel.

2.Installtheappropriatefieldsuppliedconduitfittingintotheheater

knockoutlocatedin the rear panel of the unit. The knockout is sized

11/4" in diameter.

NOTE: Check FIGURE 11 for heater/speed combinations that are

unacceptable.

3.Connect field installed copper ground wire(s) to the ground lug(s) on

the heater mounting plate. On models with more than one circuit, a

separate copper ground wire MUST be connected to a separate

ground lug for each circuit.

4. Route the field supplied line voltage wires for the heater to the line

side of the electric heat accessory's circuit breaker(s) or high voltage

wiring harness. Leave approximately 8" of excess wire so the break-

er or wiring harness may be moved to service. Make line voltage

connections to L3-L6 as appropriate. NOTE: If heaters without

breakers are used, route field wires to inside of unit and attach to

heater wires tagged L3-L6 as appropriate using supplied wire nuts.

5.Connect the black wire with terminal from the heater wire harness to

the loose black wire at the unit blower or appropriate speed tap if

lower speed is desired in electric heat mode.

FIGURE 10 1

6 Connect the red wire with terminal in the heater wire harness to the

loose red wire from the unit sequencer.

7.Connect the white wire from the heater wire harness to the white wire

from the thermostat at the field supplied low volt wire harness in the

control box.

8.Connect the grey and brown wires from the heater wire harness to

the blue wire from the unit 24V common. NOTE: If outdoor thermo-

stats are used for staging electric heat, connect the grey and brown

wires according to the thermostat instructions. See "Staging" in

Electrical Wiring Section of this Manual.

After completing installation of the heater, install the breaker rain shield on

the blower access panel according to the following instructions on page 8.

Ifusing a pigtail style heater, proceed to Start-Up Procedures for Auxiliary

Electric Strip Heat on page 10.

Circulating Air Blower

DeterminingBlowerSpeed

1.Turn electric power OFF.

2. From the system design, determine the total external static pressure

(ESP) for the supply ducts, return ducts and registers, diffusers,

grilles, dampers, heaters and filters.

3.To your system ESP determined in Step 2, add 0.05 In. W.C. for a

wet coil.

4. From the system design, determine the desired cooling airflow in

cubic feet per minute (CFM).

5. Locate the unit's Blower Performance Data table on the tech data

label for the unit's voltage. (The tech data sheet is attached to the

evaporator access panel on the unit.) From the table, determine the

speed tap required to achieve the desired airflow.

&See next section, Speed Taps, to set the blower motor speed termi-

nal block (speed taps) to the cooling speed determined in the pre-

vious steps.

BE SURE TO CHECK BLOWER MOTOR SPEED DATA ON THE

UNITS TECHNICAL DATA LABEL LOCATED ON THE UNIT.

NOTE: Electric heater blower wire may be attached to any "Appropriate"

speed tap See FIGURE 11notes. The yellow lead MUST always be con-

nected to the speed tap block at the common quick connect terminal. The

terminal is identified as COM.

Refer to FIGURE 18 and the appropriate unit wiring diagram included in

this manual. Wire the black wire to the required speed tap terminal to

achieve required airflow determined in Step 5.

Cooling and Auxiliary Electric Strip Heat

On Air Conditioning units with electric heat, the heat strip may be operated

on a lower blower speed than cooling (Refer to Heater Chart FIGURE 11)
